The Dynamic Mixing System by 3M is the first portable system to mix and apply filler on demand. It alleviates the need to mix filler manually, which in turn means the virtual elimination of issues such as pinholes, waste, staining, mess and over-mixing. Instead, the system offers controlled, air-free mixing where the ratio of hardener to filler is exact, with no need for guesswork.

Richard Burn of 3M’s Automotive Aftermarket Division explains: “The Dynamic Mixing System is a breakthrough in body filler technology as it removes all the guesswork and allows the mixing system to be controlled and therefore much more efficient. The optimum ratio of filler and hardener is delivered every time and can be applied as an when it is needed, saving time and money.” 

The system uses vacuum-packed filler and hardener cartridges that are manufactured in an air-free environment. No manual mixing is required and the system uses a fixed ratio of filler and hardener every time to eliminate the possibility of over-catalysation. All product is mixed in the disposable nozzle that comes with the system, so nothing is left over in the cartridges, minimising waste and clean up time.

The system can be used with DMS General Purpose Body Filler and DMS Heavy General Purpose Body Filler by 3M. Both products have a 12 month shelf life from the date of cartridge filling.
